1. Introduction The converter is designed to provide the most versatile connection possible between two RS-232 serial equipment using fiber optic cable. It allows any two pieces of serial equipment to communicate full-duplex over typical duplex fibers,or over optional single fiber up to 20km. The converter supports transparent conversion for not only RS-232 data lines, but also all RS-232 control signals. It also supports all RS-232 baud rates with no need for user configuration.
1.1 Features z Transparent conversion for all RS-232 signals z Supports RS-232 baud rate higher than 115.

2. Installation 2.1 Unpacking Check that the following components have been included: • Information CD • The device unit • DIN-rail mounting bracket If any item is found missing or damaged, please contact your local reseller for replacement. The following are available optional accessories: • Panel Mounting Bracket The bracket is used for mounting the device on a panel surface. • Commercial-rated AC power adapters: - Rated AC120V/60Hz DC7.5V 1A - Rated AC230V/50Hz DC7.5V 1A - Rated AC100V/50-60Hz DC7.
2.2 Safety Cautions To reduce the risk of bodily injury, electrical shock, fire, and damage to the equipment, observe the following precautions. • Do not service any product except as explained in your system documentation. • Opening or removing covers may expose you to electrical shock. Only a trained service technician should service components inside these compartments.
2.3 DIN-Rail Mounting In the product package, a DIN-rail bracket is installed on the device for mounting the converter in a industrial DIN-rail enclosure. The steps to mount the device onto a DIN rail are: 1. Install the mounting bracket onto the device unit as shown below: 2. Attach bracket to the lower edge of the DIN rail and push the unit upward a little bit until the bracket can clamp on the upper edge of the DIN rail. 3. Clamp the unit to the DIN rail and make sure it is mounted securely. 4.
The final mechanical dimensions after installing DIN rail mounting bracket are: -14-
2.4 Panel Mounting The device is provided with an optional panel mounting bracket. The bracket support mounting the device on a plane surface securely. The mounting steps are: 1. Install the mounting bracket on the device unit. 2. Screw the bracket on the device unit. 3. Screw the device unit on a panel. 4. Make sure that there are proper heat dissipation from and adequate ventilation around the device. Do not place heavy objects on the device.
The screw locations and final dimension are shown below: -16-
2.5 Applying Power The power specifications of the device are: Operating Voltage +7 ~ +30VDC Power Consumption Max. 2.4W @30VDC The device provides two types of power interfaces, terminal block and DC power jack for receiving DC power input from external power supply. Using Terminal Blocks Either DC1 interface or DC2 interface can be used to receive DC power from an external power system. Or, DC2 also can be used to deliver the power received on DC1 to next device in cascading way.
Power wires: 24 ~ 12AWG (IEC 0.5~2.5mm2) Install the power source wires with the plug properly. Screw the wire with plug securely. Then, plug in DC1 contacts. If cascading the power to next device is needed, install the power wires and plug for another switch. Then, use DC2 contacts. Note: Only up to four device units can be cascaded to receive power from one main power input source.
Using DC Power Jack DC Jack Connector: Jack D 6.3mm D 2.0mm AC Power Adapters: Optional commercial rated adapters are available for purchasing. Rated AC120V/60Hz DC7.5V 1A Rated AC230V/50Hz DC7.5V 1A Rated AC100V/50-60Hz DC7.5V 1A Rated AC240V/50Hz DC7.5V 1A Connect power adapter DC plug to the DC power jack of the converter before connecting to the AC outlet. Connect the power adapter to the AC outlet. Note: Before you begin the installation, check the AC voltage of your area.
2.6 Power Failure Relay Output The device provides a relay output to report power failure event to a remote alarm monitoring system. The replay output is provided with two contacts labeled PF+ and PF- in the terminal block interface. Use the provided 2P terminal plug for signal wiring and plug into the PF+/ - contacts. The function is designed as : Power is normal PF+ contact is shorted with PF- contact. Power failure PF+ contact is disconnected with PF- contact.

2.8 Making Fiber Port Connection Depending on the model purchased, the fiber port provides one of the following connector types: Duplex ST, Duplex SC, Single SC. Connecting Multimode Duplex Fiber Make sure the RX-to-TX connection rule is followed on the both ends of the fiber cable. Connecting Single Mode Duplex Fiber Note: Make sure the RX-to-TX connection rule is followed on the both ends of the fiber cable.
Connecting Single Mode Single Fiber For Bi-Di (Bidirectional) single fiber connection which use two different wavelengths for TX and RX respectively over single SM fiber cable, only one connector is provided on the fiber port and only one fiber cable is used. Network Cables Multimode (MMF) - 50/125, 62.5/125 Single mode (SMF) - 9/125 Fiber Distance between two devices Model Connector Fiber KSC-200-T ST MMF Distance (ref. max.
2.9 Application The converter can be used to extend the distance between two serial devices via fiber cables. The distance can be 2km, 20km, and even up to 100km. The following example illustrates a PC performs serial communocation with another RS-232 device far apart: The converter converts all signals of the COM port of the PC to optical signals and sends to the other converter far apart over fiber cable.
